Next Big Future: Creating spacetime shortcuts with gravitational waveforms without exotic matter for possible FTL communication and FTL travel

February 29, 2016

A region-delimited gravitational wave field can be constructed, such that a subset of geodesics crossing this region will move faster than nearby geodesics moving entirely inside flat spacetime, along a preferred direction.

Sourced through from:

Does this idea make possible the construction of a functioning ansible? Does it violate causality?
